Cryo-EM structures of PP2A:B55-Eya3 and PP2A:B55-p107 define PP2A:B55 substrate recruitment

The paper determines the cryo-EM structures of PP2A:B55 bound to p107 and Eya3, revealing distinct substrate and regulator recruitment mechanisms and conserved motifs.

Cryo-EM structures of PP2A:B55-FAM122A and PP2A:B55-ARPP19

The paper reports cryo-EM structures of PP2A:B55 bound to phosphorylated ARPP19 and FAM122A, revealing distinct binding mechanisms and providing insights for therapeutic development.

PP2A/B55α substrate recruitment as defined by the retinoblastoma-related protein p107

This study identifies a conserved SLiM in p107 that mediates B55 recruitment and dephosphorylation, revealing a general mechanism for PP2A/B55 substrate recognition.

1H, 15N and 13C sequence specific backbone assignment of the MAP Kinase Binding Domain of the Dual Specificity Phosphatase 1 and its interaction with the MAPK p38

The paper reports the backbone assignment of DUSP1's MAPK binding domain using [13C,15N]-labeled protein, enabling further studies on its interaction with p38 MAPK.

The interaction of p38 with its upstream kinase MKK6

This study identifies the binding interface between MKK6 and p38 using NMR and ITC, showing distinct interaction patterns compared to phosphatases.

Choice of PP1 catalytic subunit affects neither requirement for G-actin nor insensitivity to Sephin1 of PPP1R15A-regulated eIF2αP dephosphorylation

The paper shows that the choice of PP1 catalytic subunit does not affect the requirement for G-actin or sensitivity to Sephin1 in PPP1R15A-regulated eIF2αP dephosphorylation.
